At the moment you have to first convert the image sequence into a movie file as FCP X cannot directly import image sequences. There is many ways of converting the image sequence including using Apple Motion to import and convert or the Quicktime 7 Player.
We expect to have a better solution to timelapse / hyperlapse shortly.
Hi, so i'm also using lock and load to stabilize my hyperlapses, and in hyperlapses there's not just verticle motion but sometimes there are shakes horizontally as well. I was wondering if there's a way that you can stabilize thesideway shakes in Lock and Load.
